    cis-B7:CD28 Interactions at Invaginated Synaptic Membranes Provide CD28 Co-Stimulation and Promote CD8+ T Cell Function and Anti-Tumor Immunity

    Scientists reported that CD8+ T cells displayed B7 ligands that interacted with CD28 in cis at membrane invaginations of the immunological synapse as a result of membrane remodeling driven by phosphoinositide-3-kinase and sorting-nexin-9.

    Genetic Mapping Reveals Pou2af2/OCA-T1–Dependent Tuning of Tuft Cell Differentiation and Intestinal Type 2 Immunity

    Researchers exploited differences between inbred mouse strains to identify an epithelium-intrinsic mechanism that regulated tuft cell differentiation and tunes innate type 2 immunity in the small intestine.

    Abstract

    LXR Signaling Controls Homeostatic Dendritic Cell Maturation

    The authors found that the engulfment of apoptotic cells triggered homeostatic maturation of type 1 conventional DCs (cDC1s) within the spleen, and that this process could be mimicked by engulfment of empty, nonadjuvanted lipid nanoparticles.

    Abstract

    ARG1-Expressing Microglia Show a Distinct Molecular Signature and Modulate Postnatal Development and Function of the Mouse Brain

    Investigators described a microglial subtype expressing the enzyme arginase-1 that was found predominantly in the basal forebrain and ventral striatum during early postnatal mouse development.

    Neonatal Immune Challenge Poses a Sex-Specific Risk for Epigenetic Microglial Reprogramming and Behavioral Impairment

    When the authors mimicked an early systemic viral infection or applied murine cytomegalovirus systemically in neonatal female and male mice, only male adolescent mice presented behavioral deficits, including reduced social behavior and cognition.

    Skin Basal Cell Carcinomas Assemble a Pro-Tumorigenic Spatially Organized and Self-Propagating Trem2+ Myeloid Niche

    Within the highly proliferative neighborhood, scientists found out that TREM2+ skin cancer-associated macrophages supported the proliferation of a distinct tumor epithelial population through an immunosuppression-independent manner via oncostatin-M/JAK-STAT3 signaling.

    Diet-Mediated Constitutive Induction of Novel IL-4+ ILC2 Cells Maintains Intestinal Homeostasis in Mice

    Researchers revealed a unique group 2 innate lymphoid cells (ILC2) subset in the mouse intestine that constitutively expressesed IL-4 together with GATA3, ST2, KLRG1, IL-17RB, and IL-5.

    Anti-Human-TIGIT Agonistic Antibody Ameliorates Autoimmune Diseases by Inhibiting Tfh and Tph Cells and Enhancing Treg Cells

    Scientists generated anti-human-T cell immunoreceptor with Ig and ITIM domains (TIGIT) agonistic monoclonal antibodies (mAbs) and generated human-TIGIT knock-in mice to accurately evaluate the efficacy of mAb function.

    Innate Virus-Sensing Pathways in B Cell Systemic Autoimmunity

    Innate immunity plays an instrumental role in the induction of adaptive antiviral immunity. The authors review how inborn errors of innate immunity can instigate B cell autoimmunity.
